Argon in the field of chemical production of raw materials in the safety of storage and transport specifications

1. Introduction

Argon is a colorless, odorless, non-toxic non-metallic inert gas, widely used in chemical, metallurgy, electronics and other fields. In the field of chemical production raw materials, argon is usually used as a protective gas, reaction medium and transmission medium. In order to ensure the safe storage and transportation of argon, this article will introduce the relevant specifications in detail.

2. the physical and chemical properties of argon

Argon is a rare gas in the atmosphere, the molecular formula is Ar, and the atomic number is 18. Under normal temperature and pressure, argon is a colorless, odorless, non-toxic gas, and it is not easy to react with other substances. Argon is slightly denser than air, has a melting point of -186.9°C and a boiling point of -186.0°C. Hazard

of Argon 3.

Although argon itself is non-toxic, at high concentrations, argon can cause a decrease in the oxygen content of the air, which may cause a suffocation hazard. In addition, liquid argon in contact with the skin can cause frostbite. Therefore, during storage and transportation, it is necessary to pay attention to safe operation.

4. Argon storage specifications

1. Storage facilities: Argon should be stored in special cylinders, which should meet relevant national standards and be inspected regularly. Storage facilities should be set in a well-ventilated, dry and cool place, away from fire, heat and direct sunlight.
2. Storage capacity: The storage capacity shall be determined according to the production demand and safety requirements, and shall not exceed the specified maximum storage capacity.
3. Storage identification: obvious safety identification and warning signs shall be set up in storage facilities to indicate the name, danger and emergency measures of stored materials.

5. argon transport specification

1. transport vehicles: transport argon vehicles should comply with the relevant national standards, with the corresponding safety facilities and fire facilities. The condition of the vehicle should be checked before transportation to ensure safety and reliability.
2. Transport personnel: transport personnel should be professionally trained, with appropriate safety awareness and operational skills. During transportation, we should be vigilant and deal with abnormal situations in time.
3. Transport packaging: Argon cylinders should be packaged in accordance with national regulations to ensure that they are firm and sealed to prevent air leakage and damage. The package should be marked with the name of the substance, the danger and emergency measures.
4. Transportation route: The transportation route shall be safe and reliable and avoid passing through sensitive areas such as densely populated areas and important facilities. During transportation, traffic rules should be observed to keep the speed stable.

6. Safety Operation Specification

1. Before using argon, the steel cylinder should be checked to confirm that there is no leakage before use.
2. During use, the room should be kept well ventilated to prevent suffocation.
3. Operators shall be professionally trained and possess corresponding safety awareness and operation skills. During the operation, we should be vigilant and deal with any abnormal situation in time.
4. After use, the cylinder valve should be closed and the cylinder should be stored in the designated place.

7. emergency measures

1. When a leak occurs, the cylinder valve should be closed immediately, and the personnel in the leak area should be evacuated to a safe area.
2. In the event of a fire, immediately use a fire extinguisher to extinguish the fire and call the fire alarm.
3. In case of suffocation, the patient shall be immediately moved to a well-ventilated place and emergency measures such as artificial respiration shall be taken.

8. Conclusion

In short, in order to ensure the safe storage and transportation of argon in the field of chemical production raw materials, it is necessary to strictly abide by relevant norms and standards, strengthen safety management and operation training, and improve safety awareness and skill level. At the same time, a sound emergency plan and rescue system should be established to ensure that accidents can be dealt with in a timely and effective manner.
